FLUE CLEANER.

WITNESEEEC y NITED STATES FRED L. MOGAHAN, OF INDIANAPOLIS, INDIANA.

FLUE-CLEANER.

SPECIFICATIQN forming part of Letters Patent No. 313,509, dated March 10, 1885.

Application filed May 23, 1884.

To all whom it may concern.-

Beit known that I, FRED L. MCGAHAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a newr and useful Improved Floc-Cleaner, of which the following is a specification.

My invention relates to an improved iiuecleaner of that class which operate by directing ajet of steam through the flue.

The objects of my improvement are to discharge the steam -j et with sudden force through the tlue, and to automatically shut otf the iiow of steam while changing the` cleaner from one flue to another.

The accompanying drawings illustrate my invention,

Figure l represents a longitudinal section of my device; Fig. 2, an elevation of the discharging end. Fig. 3 is a section of a modified form ofthe Hue-plate.

a is a hollow cylindrical discharge-jet having its interior divided into two chambers communicating With each other through a central opening, b, closed by the valve cl.

c c are annulardischarge-openings near the periphery of a, and communicating with its interior. Valve d has a stem, e, extending forward through the forward end of a.

fis an annular plate having central arms, r/ g, which pass through the walls of a in slots h between the openings c, and connect said platef with the end of valve-stem e. Platef may have a conical surface, as shown iu Fig. l, or flat, as shown in Fig. 3.

z' is a tube screwed into the jet a, forming a hollow handle for the implement.

k is a T-coupling having its outer end closed by a stuffing-box, Z.

m is a rod having one end connected withl valve d, and extending through pipe t' and stuftng-boxl, terminating in a knob or handle.

a is a handle connected by a swivel-joiut,j, to a sleeve, o, which slides over pipe j, and is adjustably secured thereon by a set-screw, p. Handle n terminates in a broad surface, r, adapted to be pushed against by the body of the operator.

sis the steam-inlet, to which a hose or steampipe provided with a flexible coupling is in use attached.

In operation, the cleaner having been connected with a steam-supply and the ends of the boiler-fines exposed, steam is admitted to (No model.)

the cleaner through inlet s. Valve d is kept from closing by the operator pulling outward,

on rod m until all condense-Water is blown out through the openings c. released, the steam-pressure against valve d at once closes it and the flow of steam is cut oli". The enlarged end of jet a, having the openings c, is then inserted in the open end of one of the iiues, and the opening closed by plate j', which rests against the end of the flue. The operator now gives a sharp push against the rear end of the implement, or against handle a, and the implement moves slightly further into the flue, while plate f, held stationary by the end of the flue, operates through stem e to open valve d, and the steam rushes suddenly and forcibly through the annular openings e and along the interior walls of the tlue, blowingV out all soot and ashes. As soon as the operator ceases to push against the implement, the valve is automatically closed by the pressure of steam behind it, and the iiow of steam thereby stopped while the cleaner is moved to another flue.

Heretofore in this class of cleaners the steamvalve has been loca-ted in the supply-pipe, and the jet of steam has not been cut off by the removal of the device from the flue.

I claim as my invention- 1. A flue-cleaner consisting of the following elements, namely: a tube having an inlet for steam, a hollow discharge-jetv secured to one end of said tube, a plate adapted to cover the open end of a flue and to slide over the exterior of said jet, and a valve seated within said discharge-jet and connected with said plate,

all combined substantially as and for the pur-v pose specified.

2. In a flue-cleaner, the combination of discharge-jet a, having annular openings c, valve d, and plate f, substantially as specified.

8. In a uecleaner, the combination, with discharge-jet a, tube i, and valve d, of stuffing-box Z and rod m, whereby said valve is operated in the manner and for the purpose set forth.

4. In a fine-cleaner, the combination, with tube t' and jet ,'of sleeve o, having a handle, a, arranged as described, substantially as and for the purpose specified.
